Better Sleep Leads to Better Sex, Which Leads to Better Sleep

According to a large new study, women over age 50 who get fewer than seven hours of sleep are less likely to report being sexually active than their peers who sleep more, a problem that increases with age.

Sleep disorders can also interfere with sex. Research suggests that men with obstructive sleep apnea, a condition marked by snoring and breathing difficulties, have decreased levels of sexual activity, possibly because they produce lower amounts of testosterone. Sleep apnea can also increase the risk of cardiovascular problems, which may be related to sexual dysfunction.

But the reverse appears to be true, too: Another recent study that looked at sleep and sex in college students found that for those in romantic relationships, every extra hour they slept corresponded to higher sexual desire, greater vaginal lubrication and a 14% increase in the chances of getting frisky the next day. That’s probably because a good night’s sleep leaves us feeling refreshed, relaxed and energetic — all important for feeling sexy.

The reasons are largely chemical in nature. After orgasm, our bodies release significant amounts of the “cuddle hormone” oxytocin, which lowers levels of the stress hormone cortisol, resulting in deep relaxation.

Sex also has gender-specific benefits. “For women, estrogen levels increase after sex, which can enhance a woman’s REM cycle for a deeper sleep. In men, the hormone prolactin is secreted after orgasm and has been tied to sleepiness,” explained licensed psychologist Rachel Needle, co-director of the Modern Sex Therapy Institutes.

Yeah, yeah — there’s just too much to do. But you need to make time for your health and for your spouse. Go to bed early tonight together!
